Efficient keyword spotting using time delay neural networks

  title={Efficient keyword spotting using time delay neural networks},
  author={Samuel Myer and Vikrant Singh Tomar},
This paper describes a novel method of live keyword spotting using a two-stage time delay neural network. [] Key Method The model is trained using transfer learning: initial training with phone targets from a large speech corpus is followed by training with keyword targets from a smaller data set. The accuracy of the system is evaluated on two separate tasks. The first is the freely available Google Speech Commands dataset. The second is an in-house task specifically developed for keyword spotting. The…
